To all 1077/0771, it may concern/:

Be it known that LlVILnnLM Minima subject of the King of Prussia, GermanEmperor, residing at Viersenerstrasse 19, Mnchen-Gladbach, Germany, haveinvented certain new and useful Improvements in Valves; and I do herebydeclare the following to be a full,clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters and figures of reference markedthereon, which form a part of this specification.

This invention relates to lift-valves for compressors, blowing-engines,pumps, and the like, whose valves have a spherical form, either concaveor convex, corresponding to that of their seat.

l am aware that lift-valves having a spherical face have been made; butthese valves have been provided with stems and are not capable to movein all directions.

The present invention has for its object a valve capable of being liftedfrom its seat and also capable of having' any desired lateral positionand turning` within limits and still effectively seat itself.

Referringl to the drawings, in which like parts are similarlydesignated,Figure 1 is a section showing' a valve whose convex sphericalsurface cooperates with aseat of complementary form. Fig. 2 is a sectionof a similar valve springurged. Fig. 3 is a modification of a simplelift-valve, the lateral movement and the lift of which is limited by aring. Fig. 4 is a valve whose concave face cooperates with a convexseat. Figs. 5 and 6 are sections of modifications of the form of thevalve itself. Figs. 7 and 8 illustrate permissible lateral movement ofthe valve to .still maintain an effective closure. Fig. 9 shows astructure of valve capable of being used in a horizontal position. Figs.10 and 11 are sections showing modifications of spring-urged valve. Fig.12 is a plan view of the valve a., Fig. 10. Figs. 13 and 14 show otherforms of the seat. ln Figs. 13 and 14 the scat has a single port 20'.

Referring more particularly to Fig. 1, a. is a valve having a sphericalsurface and a central opening 13 and flange 14, the closing-surface ofthe valve being convex. This valve seats on a concave element 15, havingcircular seating-surfaces Z1, projecting above the seat and arranged onthe surface of a sphere, whose radius is the same as that of the face ofthe valve, and distanced therefrom is a spider c, which serves to limitboth the upward movement or lift of the valve as well as its lateralmovement or play.

The operation is as follows: Air or other compressible fluid will passthrough ports 16, which are preferably substantially annular save forthe ribs a', and lifts the valve a from its seat and forces it againstthe spider c, permitting the air to pass through the ports 16, aroundthe valve and partly through the central opening 13 and the spider. Thevalve in reseating can shift laterally in any direction, the limit ofmovement being' the distance between the flange 14 of the valve and thearms of the spider c or the ring y, carried at the extremities of thespider-arms, so that the valve in falling will always seat perfectly.

ln Fig. 2, which is similar in structure to Fig. 1, the spider c has acentral recess 17, in which is a spring e, urging the valve to its seat,the opening through the valve instead of being circular being sectionsof annuli 13h The operation of this valve is precisely the same as thatof Fig. 1 With the exception that it takes a greater pressure to liftthis valve than that shown in Fig. 1. The spring e is free to bend inany lateral direction, and thereby partakes of any lateral movement ofthe valve.

In Fig. 3 the Valve (t is retained by ring (l, the lift and lateralmotion of the valve being liiinited by said ring.

Fig. 4 is a spherical valve of the form reciprocal or complementary tothat shown in Fig. lwthat is, the seat instead of being concave isconvex and the concave face of the valve a is seated on thering-surfaces The valve is provided with aflange, as in the othe'ilforms, and limited in its lateral as well as vertical movement by thespider c.

Fig. 5 is a section through the hollow valve a?, which is in the form ofa plano-convex lens.

Fig. 6 is a section of a valve a. in the form of a concave-convex lens.

Figs. 7 and 8 show extreme right and left positions of the valve a,which has a movement about the center o of the sphere of which the valveforms a portion.

In Fig. 9 the valve is shown made of sheet metal or cast having acentral perforation 13,

surrounded by an upturned flange 18. The spider c has a central bore orsocket 17, in which is closely litted a coil-spring c, the flange 18fitting within the center of the spring, said spring projecting beyondits socket in the spider, the free end carrying the valve. Thisstructure permits the use of avalve in a horizontal axial position.

Figs. 10 and 12 show the valve (l, provided with lugs 19 and the ring ofthe spider c2 provided with recesses 20, three such recesses and lugsbeing' provided. IVithin the recesses are springs e2, taking over thelugs and limiting the lateral movement of the valve.

In Fig. 11 the spider is shown having acircular rim c3, around which isa coil-spring ci, taking within the liange and into the cavity of thevalve, thus serving to limit the movement of the valve. Such valves canreadily be made from cast or sheet material, are easily removable, andhave no complicated parts or wearing-surfaces. They may be termedselfgrinding valves, their movement being such as to maintain a groundseat.

In Figs. 13 and 14 other forms of the seat are shown, which can be usedwith all the described forms of valve.

vHaving thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

1. A valve comprising a casing provided with a valve-seat, an unguidedvalve-body free to move in any direction, and means in the casing tolimit the movements of said body relatively to its seat.

2. A valve, comprising a casing provided with a spherical valve-seat, anunguided valvebody provided with a complementary seating'- surface andfree to move in any direction, and means in the casing to limit themovements of said body relatively to its seat.

8. A valve, comprising a casing provided with a valve-seat, an unguidedvalve-bod y provided with a concave seating-surface and free to move inany direction, and means inthe casing to limit the movements of saidbody relatively to its seat.

4. A valve, comprising a casing Yprovided with a valve-seat, an unguidedvalve-bod y free to move in any direction, one or more springs acting onsaid valve-body to urge the same to its seat, said spring or springs,free to partake of the movements of the valve -body, and

means in the casing to limit the movements of said valve-bod yrelatively to its seat.

5. A valve, comprising a casing, provided with a valve-seat, an unguidedvalve-body provided with an encompassing-flange and Jfree to move in anydirection, an abutment in the valve-casing distanced from the valve-bodyand cooperating with its iiange to limit the movements of said bodyrelatively to its seat.

6. A valve, comprising a casing provided with a spherical seat havingports near its edges, an unguided valve-bod y provided with acomplex'nentary seating-surface, an encompassing liange and a centralpassage, said valvebody free to move in any direction, an abutment inthe valve-casing coperating with the aforesaid flange to limit themovements of the valve-body relatively to its seat, and one or moresprings acting on said body and free to partake of its movements.

7. A valve, comprising a casing provided with a spherical valve-seat, anunguided sheetmetal valve-body provided with a complementaryseating-surface and Jfree to move in any direction, means in the casingto limit the movements of the valve-body relatively to its seat and oneor more springs acting on the valve-body and partaking of its movements.

8. The combination with a spherical seat, of a valve having a formcomplementary to the seat and a flange, a spider carrying a ring at itsend distanced from the seat above the valve, said ring limiting the liftand lateral movement of the valve.

9. The combination with a spherical seat, of avalve havingacomplementaryform, a spider carrying a ring on its end and having a socket, a springheld in the socket, the freeend of which engages the valve,substantially as described.

1 0. The combination withasphericalseat,of a valve having acomplementary form, a spider carrying a ring on its end held distancedfrom the seat and a plurality of springs in the spider, each engaging'the valve, substantially as described.

In testimony that I claim the Jore ;oing as my invention I have signedmy name in presence of two subscribing witnesses.
